Examples are around if you look for them. Even with all the economic indicators looking bad, businesses that do something people need done still work.

Brent Bower of The New York Times had a nice piece along those lines over the weekend. He called it Business Opportunities Abound, Even in Bad Times. He features three specific small businesses that are growing right now. One focuses on medical discounts for low-income people, one on data security, and one is looking to invest in new business in a down market.

And it isn’t just needs driving business, either. There’s also some obvious growth in cool technology. Things that change the game. Specifically, another piece of news this weekend is a new $35 million investment in Twitter. That’s along with a series of commentaries and analyses on how Twitter can, someday, eventually, make money.

What Twitter has, in the meantime, is a huge growth in buzz and users. And it’s free. So it makes no money now, but its investors figure it will make money eventually.
